We’ve now got a wider range version of our favourite triple-axis accelerometer – it even has an onboard 3.3V regulator – making it a perfect choice for interfacing with a 5V microcontroller such as the Arduino. This breakout comes with 3 analogue outputs for X, Y and Z axis measurements on a 0.75″x0.75″ breakout board.

The ADXL326 is the latest and greatest from Analog Devices, known for its exceptional quality MEMS devices. The VCC takes up to 5V in and regulates it to 3.3V with an output pin. The analogue outputs are ratiometric: that means that 0g measurement output is always at half of the 3.3V output (1.65V), -16g is at 0v and 16g is at 3.3V with full scaling in between.

Fully assembled and tested. Comes with an 8-pin 0.1″ standard header in case you want to use it with a breadboard or perfboard. Two 2mm (0.08″) mounting holes for easy attachment.

The XYZ filter capacitors are 0.1uF for a 50 Hz bandwidth

Revision History

• As of June 12, 2024 – we’ve updated this PCB with Adafruit Pinguin to make a lovely and legible silkscreen – you may get the new PCB or the older version with vector fonts – both are identical other than the fancy silkscreen.
